Cute: Dan said he was first taken with the idea of seeing dogs doing yoga, but then the theme of cats, kittens and puppies followed

'At that moment I thought wouldn't it be great to see dogs doing yoga. I love dogs and was doing a lot of yoga as well.'Really I just was taken with the idea of seeing dogs do yoga, then the idea of cats, kittens and puppies followed.'It was something so different from my usual work and I love making these photos in order to make people smile and learn about yoga at the same time.'We find the animals every where. In the beginning we worked with our friend's dogs but of course the original pioneer Yoga Dog and Yoga Cat were our dog, Mela and our cat, Snoosh.

'There are of course some challenges working with animals but the most important aspect is to keep the dogs and cats feeling safe and actually having fun.'Patience is a key ingredient, since dogs and cats have their own ideas. All the poses are genuine yoga poses or variations which are used in yoga classes.'This is the part that's really important because the humour comes from them seriously doing real yoga.

'Ale loves this step of the work because she's the one who gets to be with the animals and play with them while I take the photographs.'I also love to work with the dogs and cats but then of course I really enjoy the creative process when we start to create an image.'Sometimes we don't really know where it's going to go but then the magic takes over and little by little it unfolds with a dog or cat doing yoga.'
